Nemesia plant named ‘Intrairedtwo’

ABSTRACT

A new and distinct cultivar of  Nemesia  plant named ‘Intrairedtwo’, characterized by its upright, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; and dark red-colored flowers with greyed orange-colored centers.

Botanical designation: Nemesia hybrida.

Cultivar denomination: ‘INTRAIREDTWO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant, botanically known as Nemesia hybrida and hereinafter referred to by the name ‘Intrairedtwo’.

The new Nemesia plant is a product of a planned breeding program conducted by the Inventor in Heidesheim and Gensingen, Germany. The objective of the breeding program is to create new compact Nemesia plants with large attractive flowers.

The new Nemesia plant originated from a cross-pollination made by the Inventor during the summer of 2007 in Heidesheim, Germany of a proprietary selection of Nemesia hybrida identified as code number N 05 82-1, not patented, as the female, or seed, parent with a proprietary selection of Nemesia hybrida identified as code number N 04 82-6, not patented, as the male, or pollen, parent. The new Nemesia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Heidesheim, Germany during the spring of 2008.

Asexual reproduction of the new Nemesia plant by terminal cuttings in a controlled environment in Gensingen, Germany since 2008, has shown that the unique features of this new Nemesia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Nemesia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Intrairedtwo’. These characteristics in combination distinguish ‘Intrairedtwo’ as a new and distinct Nemesia plant:

-   -   1. Upright, outwardly spreading and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Freely flowering habit.     -   5. Long flowering period.     -   6. Dark red-colored flowers with greyed orange-colored centers.

Plants of the new Nemesia differ from plants of the female parent selection primarily in the following characteristics:

-   -   1. Plants of the new Nemesia are more freely branching than         plants of the female parent selection.     -   2. Plants of the new Nemesia and the female parent selection         differ in flower color as plants of the female parent selection         have white-colored flowers.

Plants of the new Nemesia differ from plants of the male parent selection primarily in the following characteristics:

-   -   1. Plants of the new Nemesia are more upright than and not as         trailing as plants of the male parent selection.     -   2. Plants of the new Nemesia and the male parent selection         differ in flower color as plants of the male parent selection         have orange-colored flowers.     -   3. Plants of the new Nemesia flower for a longer period of time         than plants of the female parent selection.

Plants of the new Nemesia can be compared to plants of Nemesia hybrida ‘Intraired’, disclosed in U.S. Plant Pat. No. 18,084. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Nemesia differed from plants of ‘Intraired’ in the following characteristics:

-   -   1. Plants of the new Nemesia were more vigorous than plants of         ‘Intraired’.     -   2. Plants of the new Nemesia were more freely branching than         plants of ‘Intraired’.     -   3. Plants of the new Nemesia and ‘Intraired’ differed in flower         color.     -   4. Plants of the new Nemesia were less susceptible to root         pathogens than plants of ‘Intraired’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the spring in 16.5-cm containers in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures ranged from 14° C. to 21° C., night temperatures ranged from 7° C. to 10° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched three times and were 3.5 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
